Benzyl Bromide → HCID 10998605, compound

Participants

Reaction Steps

To a stirring solution of (2S)-2-hydroxy-4-methylvaleric acid (5.0 g) and benzyl bromide (4.95 ml) in DMF (50 ml) was added potassium carbonate (3.13 g) at room temperature. After being stirred for 12 hours, the solvent was removed by evaporation in vacuo. The residue was dissolved in ethyl acetate (100 ml) and washed with water, 1N HCl and brine successively. The organic layer was dried over magnesium sulfate and concentrated in vacuo. The residual oil was purified with silica gel column chromatography (hexane-ethyl acetate as an eluent) to give benzyl (2S)-2-hydroxy-4-methylvalerate (8.2 g) as a colorless oil.
